If the 100V unit's display becomes dark while running the PL, there may be a
problem with the backlight. If a problem is found or if the backlight is burnt out,
you will need to replace it with a new one.
With the PL-570*T1 and PL-570*S1, you can replace the backlight by yourself. How-
ever, if your model is the PL-570*L1 or the PL-570T1-24VC, you will need to ask a
Digital service person to replace the backlight. Please contact your nearest Digital
Service Center. Also, when using the PL-570*T1 or PL-570*S1, replace the back-
light following the instructions below. The part number of the replacement backlight
is "GP570-BL00-MS."
